    Benefits:

    • Extra capacity
    • Drain hole and magnetic plug to simplify maintenance
    • Fins for heat dissipation and classic styling
    • Sand cast aluminum construction for thick walls
    • Machined gasket flange for a secure seal
    • Round shape similar to stock cover

    Typical applications include GMC and Chevy trucks and SUVs, ½ and ¾ ton, with 2 or 4 wheel drive, from 1963 to 1991. Some common applications for this rear end cover are:

    • C10 & K10, 1967 to 1976
    • C20 & K20, 1973 to 1976
    • Chevrolet Blazer, 1969 to 1976
    • GMC Jimmy, 1969 to 1976
    • Suburban 10/1500, 1973 to 1981
    • Suburban 20/2500, 1973 to 1991

    Verify differential and clearance before ordering. Configurations vary. These trucks and SUVs had several possible differentials.

    Vehicles with coil suspension can have a track bar close to the stock differential cover. Vehicles with leaf suspension generally have plenty of space for a larger aftermarket part.
